Also consider that many SSRIs actually list suicidal urges as a side effect. In my transition from Celexa to Prozac to Effexor, I've found that transitioning period to be particularly bad. Not to go into too much detail but I've done things of late I never did before and my doctor has said it's likely my change in medication. They say things need to be at their worst before they can get better. That's my mantra.
